I´d like to have a diferent pattern in plan which must represent 25 cm of wall.

Because I´m using a different type o brick which cannot be cut and all walls must be the size of multiple of 25 or 12,5 cm ..

If I had this "pattern" I can also visualy calculte other thing in the plan, like the place to fill with concrete etc..

If you need I can send you the icon I have the file in vector format.
